FABRIC.

SPECIFICATION forming part of Letters Patent No. 330,787, dated November17, 1:885.

Application filed February 8, 1884. Serial No. 120,114. (No model.)Patented in Canada June 19, 1882, No. 14,979.

To all whom it may concern.-

Be it known that I, THoMAs IsHERwooD, of Westerly, in the county ofWVashington and State ofRhode Island, have invented a new and usefulImprovement in Fabrics; and I hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification.

This invention has reference to duck, sail, tent, awning. and othersimilar cloth; and it consists in weaving the same with strips forstrengthening the cloth simultaneously with the cloth proper andinterweaving such strips by springing the extra warp-threads for thesestrips from one surfaceof the cloth to the other, so as to tie the weftand warp of the strip to the cloth, whereby the strength and durabilityare much increased, as will be more fully set forth hereinafter.

Figure l is a view of a piece of cloth in which strengthening-strips areinterwoven. Fig. 2 is a sectional view of the cloth, showing the ends ofthe warp-threads and the lay of the weft or filling. Fig. 3 is asectional view of the cloth, showing the ends of the weft-threads andthe extra binding warpthread by which the strip is united with thecloth. Fig. 4. is a skeleton view of the warpthreads, the warp-beams,and the harnesses.

In the drawings, A represents the cloth, which may be duck, sail,awning, or other similar cloth woven in one, two, or more ply.

B B are the raised strips for strengthening the cloth. These strips arewoven by a series of shuttles operated by a rack or in any other of themethods used on ribbon-looms, and so that while the shuttle laying theweft in the cloth proper traverses the Whole width each one of theseries of shuttles laying the weft in the strips will move across thewarp forming the strips B, and also lay the weft'thread.

In Fig. 4, a is the warp-beam on which the warp for the body of thecloth, as also the main warp for the strengthening-strips,

is wound, and from which the same is supplied.

is the warp-beam on which the warp forming the binder-threads is wound,and from which they are supplied.

b b are the binder-threads.

b b are the heddles or harnesses by which the binder-threads are sprungso as to form sheds for the shuttles in laying the filling or weft ofthe main cloth, and the sheds for the shuttles laying the filling orweft for the strengthening-strips.

a a are the warp-threads for the cloth A proper, and a a are the heddlesor harnesses for springing the sheds of the warp.

c c are the weft or filling threads laid by the shuttles weaving thestrengthening-strips, and O the weft for the cloth proper.

Cloth for sails, for tarpaulins, tents, duck cloth, and, in fact, clothfor a large variety of purposes and uses, is strengthened by sewingstrips of cloth on the surface, and cloth with extra thicknesses formingstrips has been heretofore woven; but such strips were woven separatefrom the cloth and only secured along their edges. Such cloth is not asstrong or durable as the cloth in which the strip is intimatelyinterwoven with the cloth, as is done in my improved cloth, and itcannot be woven with as great facility as my improved cloth.

By this means of weaving this cloth I weave the top and bottom pliesboth at once, as all the shuttles gothrough at one time. So in weavingcloth with forty picks I only run the loom twenty picks, and thus make asaving of fifty per cent. in weaving the cloth.

Having thus described my invention, I claim as new and desire to secureby Letters Patent A re-enforced cloth made with the main and auxiliarywarps and the main and auxiliary wefts, said auxiliary warps formingbinders interweaving the re-enforcement and the body of the cloth andcommon to both surfaces, the said re-enforcements having double thenumber of warps and double number of fillings as the body of the cloth,substantially as described.
